HICKOK MANUFACTURING COMPANY, OF HARRISBURG, PENNSYLVANIA, A COR-PORATION OF PENNSYLVANIA CONVEYER AND GUIDE Application filed September21, 1927. Serial No. 220,992.

The present invention relates to conveying and guide mechanism forfeeding sheets, the object being to provide in connection with a simpleform of conveyer and guide, means for insuring the paper being moved toand maintaining its path along the guide.

In the accompanying drawings:

Figure 1 is a plan view in elevation of the conveyer and guide equippedwith the novel mechanism,

Figure 2 is a sectional view on the line 22 of Figure 1,

Figure 3 is a detail sectional view on the line 33 of Figure 21 In theembodiment disclosed, sheet conveying mechanism is employed, preferably1n the form of endless tapes 4 that pass around rollers 5, which rollersare driven by any suitable means. A guide 6 is located along one side ofthe set of tapes 4:, and preferably consists of an angle bar with ahorizontal flange 7 and an upstanding flange 8, the former constitutinga support for the margins of the sheets carried by the tapes 4 and thelatter acting as the guiding element for said sheets. Any suitablefeeding apparatus may be provided for delivering the sheets, one at atime on to the left-hand end of the conveyer.

The horizontal supporting flange 7 of the guide member 6 is cut away, asshown at 9, and in the opening is located a rotatable suction roller 10that is inclined to the guide flange 8, and to the tapes 4, theinclination being such that the upper face of the roller travels in thedirection to urge the sheets towards the guide flange 8. This roller maybe of any suitable structure, but as shown is of the type disclosed inmy Patent, No. 1,49%,303. It is carried by a shaft 11 journaled in a box12 that forms a part of a bracket 13 secured to the guide 6.

This shaft is provided with a deeply grooved pulley 14, around whichpasses a drive belt 15, driven by a pulley 16 on one of the conveyerrollers 5. The suction conduit l7 for the suction roller 10 is connectedto suitable air exhausting means, not shown, and is preferably providedwith a variable relief valve of well known character, shown at 18, sothat the force of the vacuum or suction in the roller can be varied inorder that the roller may properly operate on sheets of various weightsand sizes.

With this construction, it will be evident that sheets delivered to theconveyer will be carried by the tapes in a direction parallel to theguide flange 8 until they arrive over the suction roller 10, whereuponthe sheets will be caused to adhere to the upper face of the roller andbecause of its inclined relation they will be moved over until theiredges engage the guide flange 8 and will be maintained against saidguide flange, thus being properly positioned for delivery from theconveyer.

From the foregoing, it is thought that the 7 construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

What I claim, is:

1. The combination with sheet conveying mechanism and a guide for thesheets conveyed, of a suction roller disposed at an inclination to theconveying mechanism and guide, said roller acting on the margin of thesheet adjacent to the guide to move the sheets to and hold them againstthe guide, and means for creating suction in the roller to cause thesheets to adhere thereto.

2. The combination with a sheet guide, of a movable conveyer for thesheets and operating parallel to the guide, and a suction rollerassociated with the conveyor and guide and inclined to both for movingthe sheets toward the guide.

3. The combination with extended sheet conveying mechanism and a guidefor the sheets conveyed, of means in addition to said conveying meansand located between the receiving and delivering ends thereof forholding the sheets against turning and moving them to and holding themagainst the guide as they are carried along the same by the conveyer,and driving mechanism engaged with the said holding means for moving thesame with the conveyer.

In testimony whereof, I afiix my signature.

' ALBERT BROADMEYER.
